GRAINDRILL AND FERTlL-lZER-DlSTRIBUTER.

SPECIFICATION forming part of Letters Patent No. 746,676, dated December15, 1903.

Application filed April 25, 1903.

To all whom it may concern.-

Be it known that I, ROBERT A. COFFEE, a citizen of the United States,residing at Anderson, in the county of Anderson and State of SouthCarolina, have invented a new and useful Grain-D rill andFertilizer-Distributer, of which the following is a specification.

My invention is an improvement in grain and fertilizer distributer, andhas for its object the construction of adevice of. this character, onewhich will feed the grain and fortilizer to three furrows and at thesame time and one which will distribute them through the same horn orconductor, but at the same time not mix them, and which will permittheir being fed separately.

Briefly considered, my invention consists of a casing divided into aplurality of hoppers open at the bottom, said casing being mounted on aplow-beam, a rearwardly-open receptacle swingingly arranged below thehoppers, distributing-horns leading from the receptacle, and means forrocking or shaking the receptacle.

The details of construction are further pointed out hereinafter andparticularly set forth in the claims and shown in the accompanyingdrawings, in Which-' Figure 1 is a side elevation of my improveddistributor. Fig. 2 is a vertical section taken centrally through thedevice, the plow and operating mechanism being'omitted. Fig. 3

is a section about on the line 3 3 of Fig. 2.

Fig. 4 is a section on the line 4 4 of Fig. 2., Fig. 5 is a sectionalplan view; Fig. 6 is a detail perspective view showing the middle horn,parts being broken away, and showing the manner of securing it to therear of they plow-beam. Fig. 7 is a detail view of the knocker-Wheel,the plow-beam being in sec tion. Fig. 8 is a detailplan view of theupper end of one of the horns, showing mode of securing same to the box.

In the construction of my distributor I employ a plow-beam A having feetor standards A, preferably three in number, the central foot being, inadvanceof the two outer ones. These feet carry the usual points A andthe plowhas the usual handles A The plow itself forms no part of myinvention, but simply provides a support for it.

A casing or hopper B, rectangular in cross- Serial No. 154,336. onmodel.)

section and having inwardly and downwardly inclined walls, is open atthe top and bottom and is held ashort distance above theplowbeam bybrackets B, bolted at one end to. the beam and at their upper ends tothe forward side of the casing. A link B is pivotally secured to eachhandle and at its opposite end is secured to the rear side of thecasing. Beneath the casing is a shallow box-like recep tacle or tray 0,which extends in advance of the lower part of the casing and alsoslightly beyond its ends. Arms 0, ofiset adjacent their lower ends, arepivotally secured adjacent their upper ends to the ends of the cas-'ing, while their lower ends are secured to the ends of the receptaclesO; Transversely-arranged oppositely-inclined partitions D, D divide thelower part of the easing into three hoppers, which are subdivided by alongitudinal vertical partition D which extends from the bottom to thetop of the casing. This arrangement divides the easing into six hoppers,as clearlyshown in Fig. .5, all of which open into the-box O. Thepartition D is extended into the box 0, leavinga small space betweenthe'lower edge of the partition and the bottom of the box. To the rearof the partition I) and in the plane of its lower edge is the horizontalpartitions 0 supported on cleats 0 running transversely across thebottom of the box. These cleats form a series of channel-ways open atthe rear end and closed at the forward end by the front wall of the box.On one side-of the partition D are secured a number of brackets D theupper brackets being perforated, and in these brackets slide thevertical strips or cut-ofi's D each strip having a-plurality ofperforations, one above the other, in its upper' portion; The lowerportionsofthese strips extend into channels form'edjby the cleatsclosing same to the rear of'the front row of hoppers, the partition Cpreventing anything from the. rear row of hoppers from entering saidchannels. A board E is secured to the rear side of the hopper,beiugspaced from it by the guide-strips 'E, and between these stripsslide the strips or cut-ofis E Their lower ends being adapted to rest onthe partitions O and to prevent the fertilizer from falling to thebottom of the box 0, side pieces C are extended along the partitions,whereby an upper channel-way is formed above that formed by each pair ofcleats, closed at their forward ends to the partition D and at theirrear ends by the sliding strips E These last-named strips have aplurality of perforations formed adjacent their upper ends, andperforations alining with each other and adapted to aline with those ofthe strips are formed in the rear wall of the casing and in the board E.

Distributing-horns F are secured to the rear of the box B. These horns,two in number, open at their upper ends into the various channel-waysformed below the hoppers, each horn opening into an upper and lowerchannel-way. Lips F extend from the rear of the box 0 and project intothe forward cut-out portion of the horns F, as shown in Fig. 2. Theseare the outer horns, and the lips F aline with the outer channels 0 Themiddle horn F is secured to the rear of the plowbeam, and the lipleading to same from the central channel C isloDg enough to pass betweenthe plow-handles. Each of these horns is adapted to discharge in therear of one of the plow-points.

To shake the box 0, a wheel Gis journaled in any suitable manner on beamA, as by a bracket G, in advance of the casing, and on the same shaft isfixedly secured a sprocketwheel G A bracket H is secured to the top ofthe beam A, and on a revoluble shaft H in this bracket is secured asmall sprocketwheel H A sprocket-chain H connects the twosprocket-wheels. On the shaft H and rotating with it is secured a wheelH, having projections H The projections strike a pin '0 secured to thebottom of the box 0 and projecting in advance of same, and in thismanner the box is agitated and the grain and fertilizer shaken outthrough the lips into the horn.

Short rearwardly-extending bars J are attached to and project from thestandards A, and to them are attached chains the ends of which drag uponthe ground behind the discharge-spouts of the horns.

The operation of my device is as follows: Grain is placed into theforward hoppers and fertilizer into the rear hoppers. D and E are raisedand held in position by pins D and E which fit in the perforations. Therotation of the wheel G, which runs on the ground, imparts motion to itsshaft,which in turn rotates the sprocket wheel G Through the chain H andwheel H motion is imparted to the wheel H and the projections H strikingthe under side of the pin 0 shake the box 0. The grain passes throughthe channel ways formed by the cleats to the horns, while thefertilizer, falling on the partition or false bottoms 0 passes be- Thestrips neath the lower edges of the strips E and falls into the horn.The distribution of either can be cut off by lowering the strips and theexact proportion of each can be regulated by adjustment of the strips.An idler J, carried by the beam A, bears on the chain H and serves tohold the chain taut.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-- I 1. A device of the kinddescribed comprising a plurality of downwardly-open hoppers, a shallowreceptacle swingingly secured beneath the hoppers, a plurality ofdistributing-horns secured to the rear of the hoppers, means for closingcommunication between the hoppers and the horns, and means for shakingthe receptacle.

2. A device of the kind described compris-' ing a casing having aplurality of downwardly-open hoppers arranged in forward and rearwardsets, a receptacle arranged beneath and pivotally secured to the casing,upper and lower channel-ways arranged in said receptacle, the lowerchannel-ways communicating with the forward hoppers and the rearchannel-ways communicating with the rear hoppers, distributing-hornseach adapted to communicate with an upper and lower channel-way, meansfor closing said channelways, and means for shaking the receptacle.

3. The combination with a plurality of downwardly-open hoppers, ashallow receptacle pivotally secured below said hoppers, a verticalpartition extending through the hoppers and into the receptacle, cleatsarranged on the bottom of the receptacle transverse to the partition,horizontal partitions arranged on said cleats in the rear of thepartition, distributing-horns secured in the rear of the receptacle, theupper end of each horn having communication with a hopper in ad- Vanceof, and one in the rear of, the vertical partition, and means forshaking the receptacle.

4:. The combination with a plow-stock, of a casing supported thereon, avertical partition arranged in and extending below said casing, aplurality of hoppers formed in the casing, in advance of and to the rearof said partition, a movable receptacle pivotally swung below saidcasing, aplurality of horns arranged, in the rear of and extendingdownward below the receptacle, the upper end of each horn havingcommunication with a hopper in advance of and one to the rear of thepartition, and means for shaking the receptacle.
